p Specification of Letters Patent.

Application led May 13, 1908. Serial No. 432,590.

Patented July 20, 1909.

Will enable others skilled in the art to Whichv it appertains to make and use the same, reference being had the accompanying drawings, and to letters or figures of reference marked therein, which form a part of this specification.

The presentl invention relates to-coke furnaces capable of operation With or Without regeneration.- This furnace is so arranged as to provide for the heating of the air which is introduced to support combustion. Italso includes a mixer by means of which the air and vas are thoroughly diffused and intermingIed before combustion.

The furnace shown is of the double front type, consisting of two parts which are absolutely symmetrical and have a common collecting gallery.

Referring to the drawings-Figure 1 is a longitudinal section of one lialf of the furnace taken along the line A-B in Fig. 4. Y Fig. 2 shows a longitudinal section ofv half of the furnace and is vie W taken on the line (-D in Fig. 5. F ig. 3 is'a section on the lineE-F Fig. 4 .is a section on the line line I-J in Fig. 2.

In the various figures, the dempers, or valves, are shown in continuous lines in the positions they occupy when Working With regeneration.

The furnace is built of. fire brick or other vitreous material. having the capacity to resist a' high degree of heat. It is of the double front type, having a central, transversely disposed, collecting gallery (fm) and longitudinally extending coal ovens, or re- These retorts are at right angles.

torts, (10). to theV collecting galleries. Between the retorts, in the walls thereof, are vertical iiues (g, fi, and f) lconnected at their upper extremities by horizontal chambers (f). The lowerextremities of these-fines (g and i) are connected b lower horizontal vchambers (h) beneath eac oven, to which the lower extremities of the iiues (g and fi) are connected byl short passages (12).' Beneath each passage (f) with its fines is a longitudinally extending passage '(l). Into this passage ,'the lower extremities of the ues (f) open. It should be noted that the vertical passages in the Walls of the ovens are separated by a vertical, transverse partition'i the plane of the axis ofthe collecting gallery (m). 4Above each oven is a horizontal passage, a, (see Fig. l) having an opening which leads into the upper part of the oven. A vertical passage 6 for the admission of coal also leads to the oven at this point. The passage 6 may be closed at 4will by .means of a valve20.

Frein passage a, transverse passages (c) lead to a horizontal passage (d), which is over the corresponding gas passage (f). passage (d) vertical openin s (e) lead to the passage (f). The passage a) may be closed at will by means of valves (t) in apertures (6), and the openings (e) may be closed by plugs, or valves, (1))se'eFig- 2'. A damper, or valve, (p) is also provided to close the upper horizontal passage at a point between the lues (i) and the ues (g). An air gallery (t) is provided on each side of the collecting gallery (m) parallel thereto, and substantially centrally placed in regard to the body of each furnace, beneath the flues.- A passage (l) leadsdown from the front of the horizontal passage '(c), bends back around the air gallery and enters the collecting From the chamber (fm).l The draft through the pas sage Z may be regulatedvby means of the valve 4. The air galleries are connected with the outside air by suitable air passages (Z).

A second passage (5) leads from the upper portion of each furnace.' This is connectedto a suitable regenerator, orseparator, and the gas is returned tothe pipe, r, (see Fig. l). From this. pipe, suitab e connections lead to the furnace and' enter longitudinal gas retorts (y). These retorts are longitudinal gas retorts (y). These retorts are longitudinally placed in regard to the furnace and transversely in regard to the gal-V leries (t) which they cross. Directly over the gallery (t) and beneath the chamber (y).

is a chamber (u) ofsimilarextent and parallel to the chamber (y). This chamber (u) is connected to the gallery (t). 4Above the chamber. (u) andbetween it and the chamber (y) is a chamber (w). The chambers (w and u) are connected by means of Widely sepa'- rated, vertical passages- (eL-'and the chamy'ber (f) and the lues (g and i).

v ceases bers (to and y) are" connected by meansof numerous 'passages (e). The passages (h) are directly over the passage (a) and are connected thereto by means of vertical openings (e). Directly beneath the passages (h) are longiturlf"al air passages (1 and 2). These )assages s connectedv to each flue (g and i) y means ci passages 4(3).

In the operation of the furnace without re' generation, the plugs, or valves, (b and b) are opened and the dempers, or valves (p) are closed. The ovens (10) are supplied with coal and a temperature of distillation is first secured by means of gas supplied to the pipes (r) from an outside source. Vhen gas 1s given off from the coal, it enters the passage (a), from there goes through the opening (c) into the passage (d), from Which it descends through the openings (e); going down the llues (g), along the passage (h), it ascends through the passages (i) and descends through the passages (f to the horizontal passage (7c). Air is admitted from the outside at n and also at 3, from the air passages (1 and 2) at the lower extremities of the lues (g and t), and combustion occurs in the chains From the passage (7c), the product of combustion descends through the passage (l) encircling the air gallery .(t) and passes to the vcollecting chamber (m).

During the re eneration, the valves (b and l?) are closed an the valve (p) is open. The gas leaves the oven through the passage (5) and enters the regenerator, from whence it is returned to the passage (r)" entering the chamber (y) through the pipes (r). Heated air from the gallery (t) enters the chamber (u), passing up through the passages (o) to the chamber (w), is diffused and passes through the openings (a) to the chamber(y). Here the gas and air become completely mixed and enter the combustion chamber (7L), through the openings (z). The chamber (h) is directly beneath the dead wall, or bottom, of the oven. From the passage (h) the products of combustion rise through the lues (i and g) to the horizontal passage (f) fromv which they enter the lues (f) and pass to the lower horizontal passage (k), from which l they enter the passage (l) encircling the air gallery, and from there they pass to the collecting gallery (m).

It will be noted that in both methods of operation, the air passages are heated by the products of combustion which are passed in the 'immediate neighborhood thereof. In this lway complete combustion is secured.

By the arrangement of the assages described, and the use in connection therewith' p of the dampers, .(b, b and p) the furnace is ates with regeneration to one which operates without regeneration.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

l. In a coln'ng furnace, an oven, a collect ing galler` an air gallery in the hirnace structure, passages in the walls of the oyen, the said assages consistin of substantially vertical ues and horizonte passages, one of the-latter connecting the upper portions of the lues and one connecting the lower portions of art of the iiues, means for conduct ino' gas rom the retort to the upper horizon tal passage, means for admitting air to the lues and passages, and a passage leading from the lower horizontal passage, through the walls adjacent the air gallery, tothe collecting gallery. l

2. In a coking furnace, an oven, a collecting gallery, an air gallery in the furnace structure, passages in the walls of the oven, the said assages consistin of substantially vertical ues and horizonta passages, one of the latter connecting the upper portions of the liues and one connecting the lower portions of art of the lines, 4means for conductin gas rom the retort tothe upper horizon ta passage, means for admitting air to the flues and passages, a passage leading fromv yso ioo

passage between said horizontal passage and l the oven.

3. In a coking furnace, an oven, llues and passages in the walls of the oven, the latter connecting the .extremities of the former,

means for admitting air to the passages, an

In testimony that I claimthe foregoing as my invention, I have signed my name 1n
